DC-9 Overdrive is a circuit modeled overdrive plug-in that emulates the famous Ibanez® TS9 Tube Screamer. The DSP algorithms in DC-9 take into account the entire schematic, using the latest modeling techniques. This gives you an authentic analog sound that matches the character of the physical circuit. DC-9 is an Audio Unit Extension (AUv3) that works inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect. The controls expand when touched so they can be easily seen while tweaking. DC-9 brings the distinctive warm overdrive crunch to your favorite iOS DAW. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more. DC-9 gets its name from the Diode Clipper circuit used to create the distortion. Accurate modeling of the clipper by circuit simulation gives DC-9 an edge over the common distortion plug- in. The effect was carefully tuned using A/B comparisons to the original stop box. Blamsoft brings their experience creating top notch plug-ins for the desktop to iOS. The same algorithm is found in the popular Rack Extension for Propellerhead Reason. You get a desktop quality algorithm at an iOS friendly price. Tap Developer Website for sound examples. Note: Second screenshot shows the effect of touching a control.

Exciter AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Exciter AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Exciter AUv3 plug-in comes as In-App Purchase. The Red Rock Sound Exciter will allow you to improve and enhance sonic quality of signal more naturally than with equalization. Unlike traditional EQ that just turns up the existing harmonics, Exciter generates additional harmonics, therefore there is no boost in the output signal level, this maintains a clear and balanced sound. Control & Indicator Functions: • IN meter — Input Signal Level indicator; • LEVEL — control knob for the Level of the Input Signal; • HARMONICS — this knob controls the amount of generated Harmonics; • TIMBRE — sets the balance between Odd and Even harmonics; • FREQ — sets the frequency of the high pass filter in the side chain prior to the harmonics generator. For example, with a setting of 6000 Hz all frequencies above 6000 Hz will have Harmonics generated by Exciter; • HL meter — the Level meter for the Harmonics that are created; • MIX — sets the amount of Exciter enhancement added to the original signal; • LISTEN — allows you to listen to the Exciter process alone; • OUTPUT meter — Output Signal Level indicator; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. To use Exciter as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Exciter will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
